John 3

3 Jesus replied, "Truly, truly, I tell you, no one can see the kingdom of God unless he is born again.*3:3 Or born from above; also in verse 7."

4 "How can a man be born when he is old?" Nicodemus asked. "Can he enter his mother’s womb a second time to be born?"

5 Jesus answered, "Truly, truly, I tell you, no one can enter the kingdom of God unless he is born of water and the Spirit.
